Applicatin inea July a1,

This invention relates to ay railway signaling device, and its object isto *providey improved means on the locomotive of 'a train and 'onthe'permanent-lme respectively, by

which it is` indicated by an audiblesignalend of the front wall Z) ofthe conductors'v stand, by meansof rivets c. The horizontal memberof'sa-id braclzet carries a dependingr spring; casing el, of which thelower'end is closed vby a screwed cover e while the `upper serves forthe reception of a strongy draw-springV f therein, which at .its lowerKVend is attachedy to Athe cover e While its upper end is fixed toamov-vV able .disc g located in the spring casing' and having twolaterally `projecting'pins h by which it is guided in vertical slots iof' the spring casing d. The spring f yis bv the same lateral pins hsuspended in its highlyl stretched positionpfrom rearwardly directedlcatches Z cfa forked arm 7c. which Ais pivoted to a lug m on thevertical member of the bracket a andfbelow said lug connected with saidmember bv means of a spring a that tends to pull the arm '17o constantlvtoward saidlmember. Laterallv ofthe ybracket a andthe spring; casing. (Za double-armedV le- -ver o' is pivote/d at 7? to the locomotive frame.'

theupper arm of said lever being in slot-and' pin connection q, r withthe forked arm 7c.

The upper surfacelof the movable 'disc gis'V fitted with twoveyes stowhich wire cords t.

' u are fixed. One of--said cordsa, is guided over a roller 'v and ledinto theeconductors stand. whence it can be pulled upwards forstretching or tensioning the draw-spring and creating the engagementbetween'4 the lateral .pins 7Ll and the forked arm 7c, the latter beingfor thisVK purpose provided at its lower extremities with an'inclin'e fw'alongV i926. seriai no. mazza!) l which the pins h travel upwards untilthey engage* in catches Z ofthe forkedfarm The other cord t is soconnected with a valve lever of thel steam pipe on the locomotive,

that the latter sounds when the cordw Ais pulleddownwards'.v The lowerarm of the lever 0 is so arranged that an abutment plate e yhinged to ablockjz/ onfthe permanent line and Vad apte'd,f'when theline isblocked',v to be pulled into its erected position shown in Fig. 1 by anyappropriate means, liesl withfk Y in the path of'said lower lever arm.,l

As soon as thelev'er o strikes against the 'erected plate "e, the forkedarm 7c is pushed forward against theVV action ofthe springl n in ysuch awaythat the pins 7L `become disengaged therefrom so that the spring f isfreed and allowed tov jump downwards *whereby the cord t is'pulled andthe steam pipe` on the' locomotive is actuated.

'As already explained,y the device ycan beV returned to its. operativeposition by vpulling` the cord u ,fromV thefconductors stand, the

valve lever :c returning automaticallyto itsv p closing` positionby'meansofv a spring m1 act-` sound. f

What I claim, is :--v Arallway slgnaling fixed rectangular bracket on alocomotive,-a

sprin'g'casing having lateral vertical slots and a closed lower end anddepen-dingfrom said bracket, a' draw-springarranged in said casing-andat its lower end," attached to the closed lower end thereof, a movabledisc in said casing to'which theupperv en-d of said ,spring is attached.l'aterallyprojecting pins on. said .movable disc'guidedvin the slots ofsaidcasing, a forked Yarm pivoted tosaid bracket and having springconnection therewith tending toypullthe arm constantdevice, comprising aY ing thereon, whereby the steam'pipe ceases t0 Y lyV toward thebracketrearwardly directed` catches Von said forked arm adapted toengage with saidv pms when .thespring 1s' 1n its ,tensionedposition,anincline'at the lower extremities of said forked armtwo'w1revcords attached to the upper surface of saidv disc of whichone led intothe conductors stand of the locomotive serves .for pullingV saiddraw-spring into its tens-ioned position fand thefpins on said ydisc.intoeengagement With said forked arm While the other cord into itserected position when the line is is connected with the steam Valve onthe loy hloolredv and then lying Within the path or Gomotlve, adouble-armed lever uleruined the lower arm of rsaid lever, Substantially1() Y on theJ locomotive and at its upper arm in as and for the purposeset forth.
